Abstract

The triglyceride compositions of peach kernel and apricot kernel oil have been investigated by a combination of high performance liquid chromatography(HPLC) and gas liquid chromatography(GLC). The triglycerides of peach kernel and apricot kernel oil were first separated by thin layer chromatography(TLC), and fractionated on the basis of their partition number(PN) by HPLC on a C-18 μ-Bondapak column with methanol-chloroform solvent mixture. Each of these fractionated groups was purely collected and analysed by GLC according to acyl carbon number(CN) of triglyceride. Also the fatty acid compositions of these triglycerides were determined by GLC. From the consecutive analyses of these three chromatography techniques, the possible triglyceride compositions of peach kernel and apricot kernel oil were combinated into fifteen and thirteen kinds of triglycerides, respectively. The major triglycerides of peach kernel oil were those of (3×C_(18:1) 30.9%), (2×C_(18:1), C_(18:2), 21.2%). (C_(18:1), 2×C_(18:2), 10.6%), (3×C_(18:2) 3.8%), (C_(18:0), 2×C_(18:1), 1.8%), (C_(16:0), C_(18:1), C_(18:2), 1.5%), (C_(18:0), C_(18:1), C_(18:2), 1.1%) and those of apricot kernel oil were (3×C_(18:1), 39.5%), (2×C_(18:1), C_(18:2), 24.5%), (C_(18:1), 2×C_(18:2), 14.2%), (3×C_(18:2). 2.0%).
